NAIROBI, Kenya — President Kibaki of Kenya named opposition leader Raila Odinga as prime minister yesterday, implementing a long-awaited power-sharing deal aimed at resolving a political crisis that left more than 1,000 people dead.

The deal marks the first time Kenya will have both a president and prime minister. But the working relationship between Messrs. Kibaki and Odinga, which has been frosty in the past, will determine how long the coalition lasts. The two men agreed in February to share power after a dispute over who won Kenya’s December presidential election triggered weeks of unrest that killed more than 1,000 people and uprooted 300,000 from their homes.

But negotiations over the Cabinet dragged on, and the public grew impatient. Scuffles broke out for three days last week between police and residents protesting the delay in Kenya’s largest slum, Kibera.

Yesterday, Mr. Kibaki announced the new Cabinet with the 40 ministries split equally between his Party of National Unity and its allied parties and Mr. Odinga’s Orange Democratic Movement. Mr. Kibaki made the announcement a day after holding closed-door talks with Mr. Odinga.

The Cabinet includes two deputy prime ministers: the second-in-command in Odinga’s party, Musalia Mudavadi, and Uhuru Kenyatta, a Kibaki ally and son of Kenyan independence hero and first president, Jomo Kenyatta.

Messrs. Kibaki and Odinga had come under growing pressure to implement the deal. The former United Nations Secretary-general, Kofi Annan, had said he was concerned by the slow pace of forming a new government under the deal he brokered, and Secretary of State Rice also called them Monday.
